iproute2 does not need to create dummy interfaces for aliases
unlike ifconfig so we no longer do this
We now bring down all aliases and addresses properly
Split off some functions from net.lo into helpers.d/functions
so that our DHCP helper scripts can use them too :)
Deprecated interface specific setup in favour of a generic config
macchanger brings interface up now - fixes #71929
DHCP over VLAN now works - fixes #71860
Disabled modified function checking as it's far too expensive on CPU
and still isn't 100% reliable
When specifing a module that isn't emerged, you now get an error
telling you what to emerge
Removed -p option from the diff call used for function removal
